Some of your work is saved inside the browser rather than on the server — the French Production Lab and Verb Spine, the Maths practice sets, the checkpoint answers inside every study guide, and any exam paper you have started but not submitted.
A browser keeps that store separately for each web address. So
tara-deploy.vercel.app and igcse.trovva.ai are two different boxes, and
moving from one to the other looks exactly like starting again.
Your ticked study blocks and your submitted exam scores are safe either way — those are on the server and come back on their own. This page is for the rest.
Step 1 — on the OLD address (the one where your work is), press Save. It downloads one small file.
Step 2 — open this same page on the NEW address, choose that file, and press Check. Nothing is written yet — it shows you what it would do first.
Or paste the copied text here:
Step 3 — if the check looks right, bring it across.
It only ever adds. If something already exists here it is left alone unless the incoming copy clearly contains more finished work, and anything skipped is listed so nothing disappears quietly. Your study plan is merged day by day, keeping whichever copy has more ticks.
A backup of whatever is currently on this address is downloaded automatically before anything is written, so this is reversible.
